2 Claims. 1

My invention relates to an improvement in window fastener wherein it isdesired to provide a simple and effective means for locking a window orsimilar object in place in its frame.

Various means have been provided for locking windows in closed position.Some of these members engage the outer surface of the window to hold itin place. Others are provided on the inside of the window and areparticularly useful where a locking of the window from the insidethereof is desirable.

An object of the present invention resides in the provision of a windowfastener which is simple and inexpensive to manufacture. Devices havepreviously been made which adequately serve their intended purpose.However, the cost of production of such items is usually relativelyhigh. Furthermore, the locking arrangement is such that in manyinstances little difficulty would be involved in pulling the lock open.The present structure more effectively locks the windows than the usualtype of device and at the same time the structure may be produced at anextremely low price.

An added feature of the present invention resides in the provision of alock which may be punched and formed entirely of sheet metal or thelike. As a result the structure may be produced with dies upon a punchpress for a relatively low cost.

These and other objects and novel features of my invention will be moreclearly and fully set forth in the following specification and claims.

In the drawings forming a part of my specification:

Figure 1 is a perspective view of my window fastener showing the same inuse.

Figure 2 is a perspective view of one part of my device removed from thewindow.

Figure 3 is a perspective view of the other main part of my deviceshowing the construction thereof.

Figure 4 is an elevation view of the part illustrated in Figure 3.

Figure 5 is a sectional view through the assembled device showing themanner in which the two parts of the fastener contact when the device isin use.

My window fastener is indicated in general by the letter A. Thisfastener includes two main parts. The first part may be termed thekeeper part and is indicated in general by the numeral Hi. The otherpart comprises the pivoted lever part and is indicated in general by thenumeral l I. In actual practice the keeper part is usually mounted upona window, a panel, or other movable part. The pivoted lever part II isusually mounted on a fixed part of the structure, as for example upon awindow frame. In the drawings the keeper part In is shown fastened tothe sash 12 of a screen or storm window l3. 'l he pivoted part II isshown fastened to the storm window frame l4.

' The keeper part ID includes a base panel I5 having one or moreapertures l6 therethrough to accommodate fastening screws or bolts suchas ll. The base panel I5 is preferably provided along one edge with anoperating flange l9 which projects at substantially right angles fromthe panel l5 for a short distance and then is inclined from its rightangular relation along its outer edge as indicated at 20. An elongatedslot 2| is provided in the flange l9. The slot 2| permits the flange !9to be more easily grasped than would otherwise be possible. The slot 2|also permits the insertion of a tool through the device if it is founduseful or desirable.

A pair of tapered prongs 22 extend downwardly from the edge of the basepanel l5 opposite that bearing the flange l9. These prongs 22 aretapered downwardly and outwardly and are arranged at opposite ends ofthe base panel. These prongs 22 extend down into the wood of the windowsash l2 and tend to hold the keeper part 10 from movement relative tothe sash when the screw I1 is in place. Through the use of the prongs22, the device is held from movement even while supported by a singlescrew H.

A flange 23 extends upwardly from the pronged edge of the panel I5between the prongs 22. This upwardly extending flange 23 acts to supporta trough-shaped or generally U-shaped keeper 24. The rounded surface ofthe keeper is directed downwardly toward the sash 12 but the flange 23holds the base of the trough shaped element in spaced relation to thesash so as to permit the lever part of the device to be inserted betweenthe keeper 24 and the sash in the manner which will be later described.

The lever part II includes a flat body portion 25 which is tapered inform, being relatively narrow at one end 26 and being rounded andenlarged at its other end as indicated at 21. A circular depression 29is off-set from the remainder of the body 25, this depression 29 havinga marginal edge 30 which is substantially on the plane of the remainderof the tapered body 25. The depression 29 is provided with a coaxialaperture 3| therethrough for accommodation of a pivot screw or bolt 32.

The lever body 25 is provided with a flange 33 which projects atsubstantially right angles to the plane of the body 25 and follows onetapered edge thereof. The flange 33 is provided with a curved end 34which joins the marginal edge 30 of the circular depression 29 and whichextends substantially tangent thereto tor a short distance. The flangededge 33 is designed toextend beneath the rounded lower surface of thekeeper 24 when the lever is engaged with the keeper. A flange 35projects from the opposite tapered edge of the lever body 25 and also issubstantially atright angles to the plane of the body. The flange 35extends at full width fora short distance from the smaller end 26 of thebody 25 and then tapers in thickness as indicated at 35 until it mergeswith the plane of the tapered. body 25 a bestillustrated in Figures 1and 3 of the drawings. The flange 35 serves as a means of rotating thelever portion l I In operation the keeper portion H! of my windowfastener is usually secured to the window sash or other movable partwhile the lever part N is pivotally attached to the frame it the pivotbolt 32. The lever portion H is properly positioned so that the curvedend 3 of the lever portion may engage beneath the keeper part 24 of thekeeper portion [0. By' pivoting the lever it about its center the keeperportion 24 and accordingly the window or other removable part to whichit is attached may be drawn againstthe frame shoulder 31 so as tosecurely look the frame in place.

When the lever has been pivoted downwardly beneath the keeper 2 the pullis such that an outward strain against the window can not pivot. thelever N into open position. other words, the pull? of the keeper uponthe lever is such that an outward force tends to hold the leverstationary or to swing the lever toward closed position. As a result themovable part is securely fastened to the frame l4 and can not heaccidentally disengaged therefrom.

By merely pivoting the lever part I t in the proper direction theleverpart may be entirely disengaged; from the. keeper M and the movablewindow or other member may be disengaged from the: frame: ll. If desiredboth a storm window and: a. screen may be provided with similarkeeperelements rem. engage each l'ever'part H Thus either the screen or'storm window may be held in the trainer by my device.

The slottedi flange l9 may be easily" grasped by the fingers; in.placing the: storm sash or screen in position in its frame. This flangethus acts as a: handle by means: of which the storm sash or screen. maybe manipulated" a pointinwardly of the: window frame; The angularly bentflange portion 20: and the slot 21 prevent the flange.- from. slippingfrom the fingers: during this process;

In accordance with the patent statutes, I have described the principlesof construction and operation of my window fastener, and while I haveendeavored to set forth the best embodiment thereof, I desire to have itunderstood that obvious changes may be made within the scope of thefollowing claims without departing from the spirit of my invention.

I claim:
